In Sweden September 5, 1945 7 Claims.

The present invention relates to a transport container, especially for tetrahedral packages, having a bottom and an orifice which when seen in horizontal projection have the shape of two regular pentagons angularly oifset in relation to each other so that the corners of the one are located midway between those of the other, and side walls in the form of ten isosceles triangles having their bases alternately coinciding with the sides of the bottom pentagon and those of the orifice pentagon. The invention is primarily characterized by the feature that the five side wall triangles having their bases coincident with the sides of the orifice pentagon at the top merge in a collar on the container, and that on the underside of the bottom of the container a downwardly directed flange is attached, which when a container is piled on top of an identical container overlies the collar of the latter.

The invention will be more fully described with reference to the accompanying drawings, in which Fig. 1 is a vertical section alongthe line IV -IV in Fig. 4 and illustrates two containers according to the invention piled on top of each other.

Fig. 2 is a similar section of two containers piled on top of each other, according to a somewhat modified constructional form of the invention.

Fig. 3 is a perspective view of the two containers according to Fig. 1.

Fig. 4 illustrates one of these containers as seen from below.

Figs. 5 and 6 are detail sections taken along the line IVVI in Fig. 4, showing devices for attaching the containers when piling them on top of each other.

As has already been pointed out, when seen in horizontal projection, the bottom and the orifice of the container have the form of two regular pentagons angularly offset in relation to each other in such a way that the corners of one are located midway between those of the other. The sides I of the bottom pentagon are somewhat longer than the sides 2 of the orifice pentagon. The bottom of the container is formed by five isosceles triangles 3 which form a pyramid having its apex directed either upwardly (Fig. l) or downwardly (Fig. 2). The side walls of the container are formed by ten isosceles triangles 4 having their bases alternately coinciding with the sides of the bottom pentagon and those of the orifice pentagon. The five side wall triangles having their bases coincident with the sides of the orifice pentagon merge at the top in a collar 5 on the container, while the five side wall triangles having their bases coincident with the sides of the bottom pentagon are connected to the bottom triangles 3 at the bases of the latter. On the underside of the bottom, spaced from its outer edges, there is attached a flange 6 in the form of a truncated pyramid the lower edge of which is approximately coincident with the bottom pentagon of the container. The upper edge of the collar 5 and the lower edge of. the flange 6 are preferably formed as reinforcing beads I. The container is easily portable by means of a handle 8 attached in lugs 9 on opposite sides of the container near its upper end.

The containers are adapted to be piled on top or each other and to be attached so as to be easily detachable in such a way that two or more containers are united to form a unit (Fig. 3) easily portable by means of the handle of the uppermost container. A constructional form of a device for such easily detachable attachmentof the containers is shown in Figs. 4 to 6. In one of the corners of the flange 6 there, is secured on the inside a stop Ill which when the container is piled on top of another container of the same shape is adapted to overlie the bead 1 on the latter container (Fig. 5) At that side of the bottom pentagon opposite to the corner rovided with the fixed sto in there is hinged to the inside of the flange 6 a spring o erated blocking means II which also coacts with the bead 1 of the orifice of the lowermost container, as shown in Fig. 6. When the containers are piled on top of each other the blocking means H automatically snaps into engagement with the bead 1 of the orifice. In order to separate the containers the blocking means II is released by means of a suitable operating means I2 in the form of an arm or the like attached to the blocking means.

The height of the container, including the flange 5 but excluding the flange 6, is approximately equal to the basis of the isosceles triangles 4 that are inclined outwardly in relation to the vertical axis of the container. The length of the sides of the orifice pentagon is approximately equal to the length of the edges of the packages in the form of substantially regular tetrahedrons for which the container is intended. The container may hold fifteen of these packages l3 (Fig. 3) which may be readily placed in position in the container in a lower layer of ten and in an upper layer of five.

What I claim and desire to secure by Letters Patent is:

1. A transport container. especially for tetrahedral packages, having a closed bottom end and an open top end which in plan view have the form of two regular pentagons angularly offset in relation to each other so that the corners of the top pentagon are located midway between the corners of the bottom pentagon, the bottom being in the shape of a pyramid composed of five isosceles triangles whose bases coincide with the five sides of the bottom pentagon, a collar forming the open top end of the container, side walls in the form of ten isosceles triangles whose bases coincide alternately with the sides of the bottom pentagon and with the sides of the top pentagon at which latter five of the side wall triangles at their bases merge into the top end collar of the container, and a bottom flange which is attached to the underside of the bottom of the container and which, when the container is piled on top of an identical container, fits over the top end collar of the latter.

2. A transport container as claimed in claim 1, in which the bottom pyramid of the container has its apex located above a plane through the sides of the bottom pentagon coinciding with the bases of five of the side wall triangles.

3. A transport container as claimed in claim 1, in which the bottom pyramid has its apex located below a plane through the sides of the bottom pentagon coinciding with the bases of five of the side wall triangles, and somewhat above the plane a of the lower edge of the bottom flange of the container.

4. A transport container, especially for tetrahedral packages, having a closed bottom end and an open top end which is plan view have the form of two regular pentagons angularly offset in relation to each other so that the corners of the top pentagon are located midway between the corners of the bottom pentagon, the bottom being in the shape of a pyramid composed of five isosceles triangles whose bases coincide with the five sides of the bottom pentagon, a collar forming the. open top end of the container, side walls in the form of ten isosceles triangles whose bases coincide alternately with the sides of the bottom pentagon and with thesides of the top pentagon at-which latter five of the side wall triangles at their bases merge into the top end collar of the container, a bottom flange which is attached to fixed projection and a spring-pressed movable looking member which, when the container is piled on top of an identical container, cooperate with the marginal bead on the top end collar thereof for locking the two containers to each other so that they may be detached from each other upon release of the spring-pressed movable locking member.

6. A transport container as claimed in claim 4, in which the bottom flange has the form of a truncated pyramid the lower edge of which is approximately coincident with the sides of the bottom pentagon as seen in plan view.

7. A transport container as claimed in claim 4, in which the height of the container from a plane containing the bases of five of the isosceles side wall triangles, coincident with the sides of the bottom pentagon, to the plane of the upper edge of the top end collar, is approximately equal to the length of the sides of the bottom pentagon.
